Normal pricing is subject to too many variables . However NORMAL pricing was far less % wise based upon wages then ,than NOW .
Allowing primers or powders to sit on a shelf has NO relevancy in their pricing .
For the record neither do I .
By MY best calculation I've Re loaded in excess of 300K 12 & 20 gauge shotshells ,in addition to the #18 various calibers I currently load for .
When I started reloading I only reloaded 7mm Rem Mag ,.44 Magnum and 9mm in the 60's . I didn't even shoot shotgun competitively or reload for them until mid 70's .
